Can't register new users

[Migrated From Jforum.net]

Hi,

When I invoke "register new user" function through the link I get this error message:

java.lang.reflect.InvocationTargetException

Not sure what is wrong.

Thank you.

Try turning captcha off in the Admin Console (under Configurations / Enable Captcha)

I looked around and looks like captcha is not working in jforum.
Is that correct?

Is there a way to make it work?

Thanks.

It's not very clear for us why the captcha classes aren't found sometimes.

For now, you will have to keep it disabled, if you don't want to pass many hours debugging the application! (but, if you want, then let us know.. help is always welcome)
